Add a new per-group SUBPACKAGE option to bsd.man.mk. When MANSPLITPKG
is enabled, this is forced to "-man", otherwise it defaults to empty
but can be overridden by the caller.
Use this in bsd.lib.mk to install library manpages in the -dev package
instead of the base package. This is nearly always preferable, since
library manpages are usually in section 2 or 3 and are only relevant
to people with development packages installed.
For manpages which should be installed in the base package even for
libraries, add a new MANNODEV group in bsd.lib.mk. Update existing
Makefiles to use this where appropriate.

libregex: fix our mapping for \w2025-08-08T18:27:26ZKyle Evanskevans@FreeBSD.org2025-08-08T18:21:03Zurn:sha1:d0ff5773cefaf3fa41b1be3e44ca35bd9d5f68ee
A small oversight in our implementation of \w is that it's actually
not strictly [[:alnum:]]. According to the GNU documentation, it's
actually [[:alnum:]] + underscore. The fix is rather trivial: just add
it to our set explicitly, and amend our test set to be sure that _ is
actually included.

Allow -DNO_STRICT_REGEX to restore historic regex behavior2024-05-10T01:29:43ZSimon J. Gerratysjg@FreeBSD.org2024-05-10T01:29:43Zurn:sha1:f77b5b295da3146c3b601767cbc4e85e6713192c
Allow restoring the behavior of '{' as described in regex(3).
Ie. only treat it as start of bounds if followed by a digit.
If NO_STRICT_REGEX is not defined, the behavior introduced by
commit a4a801688c909ef39cbcbc3488bc4fdbabd69d66 is retained,
otherwise the previous behavior is restored.

regex: fix freeing g->charjump in low memory condition2024-02-02T18:51:54ZCorinna Vinschenvinschen@redhat.com2024-02-02T18:30:39Zurn:sha1:619f455b8fc9d05b50822387d3203f74c86fcb5c
computejumps() moves g->charjump to a position relativ to the value of
CHAR_MIN. As such, g->charjump doesn't necessarily point to the address
actually allocated. While regfree() takes that into account, the low
memory handling in regcomp_internal() doesn't. Fix that by free'ing
the actually allocated address, as in regfree().

regex: mixed sets are misidentified as singletons2023-12-22T05:19:59ZBill Sommerfeldsommerfeld@hamachi.org2023-12-21T03:46:14Zurn:sha1:8f7ed58a15556bf567ff876e1999e4fe4d684e1d
Fix "singleton" function used by regcomp() to turn character set matches
into exact character matches if a character set has exactly one
element.
The underlying cset representation is complex; most critically it
records"small" characters (codepoint less than either 128
or 256 depending on locale) in a bit vector, and "wide" characters in
a secondary array.
Unfortunately the "singleton" function uses to identify singleton sets
treated a cset as a singleton if either the "small" or the "wide" sets
had exactly one element (it would then ignore the other set).
The easiest way to demonstrate this bug:
$ export LANG=C.UTF-8
$ echo 'a' | grep '[abà]'
It should match (and print "a") but instead it doesn't match because the
single accented character in the set is misinterpreted as a singleton.

regcomp: use unsigned char when testing for escapes2023-09-25T22:49:14ZChristos Zoulaschristos@NetBSD.org2023-08-30T20:37:24Zurn:sha1:3fb80f1476c7776f04ba7ef6d08397cef6abcfb0
- cast GETNEXT to unsigned where it is being promoted to int to prevent
sign-extension (really it would have been better for PEEK*() and
GETNEXT() to return unsigned char; this would have removed a ton of
(uch) casts, but it is too intrusive for now).
- fix an isalpha that should have been iswalpha
