[C2hs] darcs patch: Allow escape sequences in the file name part of #line ...

Here's a simple patch, just to check that "darcs send" is gettin through to the list. I'm using: darcs send --edit-description The patch fixes things for non-english locales where cpp sometimes uses escape sequences in filenames or 'virtual' file names like translations of "<interactive>". Currently the c2hs lexer doesn't accept escape sequences. This patch changes that. Thu Apr 6 22:47:15 BST 2006 Duncan Coutts * Allow escape sequences in the file name part of #line directives
