From: Jakub Narebski <hidden>

Subsystem:

Add option to replace SPC (' ') with hard (non-breakable) space HTML
entity ' ' in esc_html subroutine.
Replace ' ' with ' ' for the code/diff display part in git_blob
and git_patchset_body; this is to be able to view code and diffs in
web browsers which doesn't understand "white-space: pre;" CSS
declaration.
Signed-off-by: Jakub Narebski <redacted>

For people who want to use non-CSS aware browsers, like w3m, elinks, links
text browsers, for looking at "blob" and "commitdiff"/"blobdiff" views
of gitweb.
HTH.
