Invalid escape sequence warning in builder RewriteRule

[janbrasna]

This probably was triggered by a --debug build:

/Sites/thunderbird-website/builder.py:348: SyntaxWarning: invalid escape sequence '\.'
  'RewriteRule ^(115\.[^/]+)esr/(.*)$ /thunderbird/$1/$2 [R,L]\n'
/Sites/thunderbird-website/builder.py:350: SyntaxWarning: invalid escape sequence '\.'
  'RewriteRule ^(115\.[^/]+)/(.*)$ /thunderbird/$1esr/$2 [R,L]\n'

So I'm guessing that:

thunderbird-website/builder.py

Lines 348 to 350 in 630edc6

	'RewriteRule ^(115\.[^/]+)esr/(.*)$ /thunderbird/$1/$2 [R,L]\n'
	'RewriteCond %{REQUEST_FILENAME} !-d\n'
	'RewriteRule ^(115\.[^/]+)/(.*)$ /thunderbird/$1esr/$2 [R,L]\n'

either needs \\. to escape for python and then for regexp… or using a r'…' raw string?
