This commit was manufactured to restore the state of the 2.2.7-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. Fix my own brokeness for the colon operator, when one of the arguments 1995-11-18T18:05:03Z Joerg Wunsch joerg@FreeBSD.org 1995-11-18T18:05:03Z urn:sha1:717252ea986d1a21f9839c2a1f9a22bb153f2637 was a valid integer. The actual decision between integer and string is now context-dependant on the operator being used. expr(1) didn't comply to Posix.2 and its own man page: any 1995-08-04T17:08:07Z Joerg Wunsch joerg@FreeBSD.org 1995-08-04T17:08:07Z urn:sha1:2a353a9fb4c79b3505eb5f414beeb4f326abed4e comparisions have been made as string comparisions, even in cases where both operands clearly qualified as integers. The fix is to make the parser properly analyzing whether an operand is a valid integer or not.

Note that some patches are still needed in that directory. I (Joerg) finished most of Philippe's cleanup. /bin/sh will still need *allot* of work, however.
