New Revision: 1172732

URL: http://svn.apache.org/viewvc?rev=1172732&view=rev
Log:
Fix issues found by PVS-Studio static analyzer:

mod_mime_magic:
cut'n'paste error rsl_encoding vs. rsl_separator, also simplify code a bit

mod_header:
wrong string initialization (leading to segfault if format argument is missing)

util_win32: duplicate sizeof (untested; Windows people, please review)

PR: 51542
