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@

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@

Return only the FILE *, and require only that to close subsequently. Having to manage the file descriptor too makes using these functions unnecessary complex. millert@ agrees

Not all commits will share the same author timestamp. This test would fail when run at the wrong time of day as found out by op@'s regress runner. ok op@
