Subject: gitweb: Move generating page title to separate subroutine
X-Git-Tag: v1.7.2-rc0~111^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=efb2d0c5dcea1069bae2d26c9534e2025ee63e66;p=git.git

gitweb: Move generating page title to separate subroutine

get_page_title subroutine is currently used only in git_header_html.
Nevertheless refactoring title generation allowed to reduce indent
level.

It would be used in more than one callsite in the patch adding caching
activity indicator to gitweb.
