From r..@ai.mit.edu (Robert S. Thau)
Subject Another patch for groups with multiple lines in .htgroup
Date Wed, 25 Oct 1995 23:51:08 GMT
Here's a substantially simpler patch for the .htgroups problem.  It
reuses the existing code wherever possible, and introduces relatively
little entirely new stuff.

This patch cuts back dramatically on consing for .htgroups reading
(only allocating enough memory for a single line).  For simplicity's
sake, it retains the 8K restriction on the length of single lines in
the .htgroups file; this is at least backwards compatible with
everybody, and I don't expect it to pose a serious problem for anyone
in practice.
