diff: use pycompat.{byteskwargs, strkwargs} to switch opts b/w bytes and str

patch: make regular expressions bytes by adding b''

dispatch: use pycompat.maplist() instead of map() to get a list

color: fix grammar in help text

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.

pager: improve support for various flavors of `more` on Windows Hardcoding 'more' -> 'more.com' means that 'more.exe' from MSYS would need to be configured with its *.exe extension. This will resolve to either one, as cmd.exe would have done if the command ran through the shell. Something that's maybe problematic with this is it comes after 'pageractive' and various ui configs have been set by the calling method. But the other early exits in this method don't undo those changes either.

statfs: avoid static allocation Previously we have "static struct statfs" to return a string. That is not multiple-thread safe. This patch moves the allocation to the caller to address the problem.

statfs: change Linux feature detection Previously we check three things: "statfs" function, "linux/magic.h" and "sys/vfs.h" headers. But we didn't check "struct statfs" or the "f_type" field. That means if a system has "statfs" but "struct statfs" is not defined in the two header files we check, or defined without the "f_type" field, the compilation will fail. This patch combines the checks (2 headers + 1 function + 1 field) together and sets "HAVE_LINUX_STATFS". It makes setup.py faster (less checks), and more reliable (immutable to the issue above).
