Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Check if yasm supports a nasm-specific syntax we use (it doesn't in 0.5.0, which is still common in Linux distros, and does in 0.6.0). Disable it if we don't, attempting to fallback to using nasm. Thanks to Mike Frysinger for the patch. Fixes Bugzilla #393.
