Subject: Add EndsWithC(char *s, int c) and call it in some initial places.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/f34427874df972004ce8a285145f6fc738f08595?ds=inline;hp=40009883832750cb536db4d41f500c0ad41005de

Add EndsWithC(char *s, int c) and call it in some initial places.
EndsWithC returns true if non-NULL string s ends with a c before the
terminating NUL.
