statfs: detect more filesystems on Linux Previously, the code only has what manpager says. In <linux/magic.h>, there are more defined. This patch adds filesystems that appear in the current Arch Linux's /proc/filesystems (autofs, overlay, securityfs) and f2fs, which was seen in news.

repair: use context manager for lock management If repo.lock() raised inside of the try block, 'tr' would have been None in the finally block where it tries to release(). Modernize the syntax instead of just winching the lock out of the try block. I found several other instances of acquiring the lock inside of the 'try', but those finally blocks handle None references. I also started switching some trivial try/finally blocks to context managers, but didn't get them all because indenting over 3x for lock, wlock and transaction would have spilled over 80 characters. That got me wondering if there should be a repo.rwlock(), to handle locking and unlocking in the proper order. It also looks like py27 supports supports multiple context managers for a single 'with' statement. Should I hold off on the rest until py26 is dropped?

gitweb: use monospace font for commit messages Commit messages often contain vertically aligned text. The default paper style already uses monospace fonts for rendering commit messages. And, AFAICT, a number of Git servers also render commit messages with monospace. It seems like the reasonable thing to do. This commit converts all instances of the full commit message in the gitweb style to render with monospace.
