Add two template variables, expose html language code and language direction.
Added only_committed_changes config setting, which speeds up wiki refresh by querying git to find the files that were changed, rather than looking at the work tree. Not enabled by default as it can break some setups where not all files get committed to git.
fix eq
deal with the case where oldrev is the same as newrev
guard against lastrev being "" just in case
minor opt
disable only_committed_changes when uncommitted files are created by plugins
autoindex and tag use transient underlay when not committing, so do not need to disable only_committed_changes
comments: Write pending moderation comments to the transient underlay to avoid conflict with only_committed_changes.
note cgid
update with new features to deal with large sites
search: Added googlesearch option, which makes it search google rather than using the internal xapain database. (googlesearch plugin is too hard to turn on when xapain databases corrupt themselves, which happens all too frequently).
typo
Merge branch 'master' of ssh://git.ikiwiki.info
