search_regex pager variable patch

[Will Fiveash]

In case anyone is interested I've attached a small patch that provides a
search_regex pager variable which can be set via message-hook to
initialize the search expression when entering pager mode.  For example
when I get mail from newsbi...@sans.org which uses " --" to delimit each
article summary in the mail body I use the following in my ~/.muttrc to
set the initial search regex so I can just hit 'n' to search for "^ --".

message-hook '~h "^from: .*<newsbites@sans\.org>$"' 'set search_regex="^ --"'

--
