it's not printf-like so %s don't make sense. Tweak the order of the arguments to obtain the intended output.

patch from Josiah Frentsos, thanks!

Backup references clutter the log view too much now that we display labels next to commit messages. They were accidentally added to the log and diffs view by me, via build_refs_str(), when support for listing backup references was added to the ref view.

When the terminal becomes smaller horizontally we did not properly account for remaining columns and the log message of a commit could overflow into the next line, garbling the display.

No behaviour change as the end result of the rewritten checks should be the same as before. We are just doing less work where possible. Patch by James Cook

Prevents ftruncate() errors due to bogus file descriptors passed from gotwebd once the repository layer runs out of temporary files to use for deltas. Have gotwebd open the maximum amount of required temporary files for now. A proper fix which scales to lower ulimit -n settings can be implemented later. Problem reported by patrick@

got_gotweb_closefile() already takes care of rewinding before truncating and closing, so no need to replicate here. ok stsp@

no need to be so loud when a client disconnects earlier than expected, log it only in verbose mode. Don't log GOT_ERR_CANCELLED too since that is only used to communicate the callers that we need to stop. ok stsp@

ok stsp@

makes diff prettier and easier to read; instead of the label we have the function name in the hunk line.

build_refs_str() can succeed returning a NULL string if a commit has some refs pointing to it but that were all filtered out, resulting in a NULL-deref. ok stsp@
