" tcsh.vim: Vim syntax file for tcsh scripts " Maintainer: Gautam Iyer <gi1242@gmail.com> " Modified: Thu 17 Dec 2009 06:05:07 PM EST " " Description: We break up each statement into a "command" and an "end" part. " All groups are either a "command" or part of the "end" of a statement (ie " everything after the "command"). This is because blindly highlighting tcsh " statements as keywords caused way too many false positives. Eg: " " set history=200 " " causes history to come up as a keyword, which we want to avoid.
