+     denote special characters such as umlaut, adiaresis, etc.
+     These characters return true for isalpha/isalnum. Ignore them
+     because they break parsing (Martin Kraemer)

-HOW TO RELEASE TCSH
-
-1)  Update version number and date in patchlevel.h
-2)  Note the new version and date in Fixes
-3)  Updated tcsh.man to have the new version and date also
-    (two separate lines, with the date in different formats)
-4)  Commit changes into CVS
-5)  Tag the release with TCSHx_yy_zz where
-	x  == REV
-	yy == VERS
-	zz == PATCHLEVEL
-    from patchlevel.h (the new values you picked)
-6)  Export the code using the new tag you created.  Rename
-    the directory from "tcsh" to "tcsh-x.yy.zz" and create
-    tcsh-x.yy.zz.tar.gz (or tcsh-x.yy.tar.gz for public
-    releases where zz [PATCHLEVEL] is zero)
-7)  Export the previous release as well
-8)  Remove files that should not be in a release:
-    - Announce*
-    - Copyright
-    - Makefile.ADMIN
-    - RELEASE-PROCEDURE (this file)
-9)  Generate a "diff -urN" between the two directories you
-    have exported, save it in patchz.gz (z is PATCHLEVEL)
-10) Make the patch and the source tarball available on ftp
-11) Mail an announcement to tcsh@mx.gw.com
-12) Mail the patch to tcsh-diffs@mx.gw.com
