The format of the `patterns` attribute seems to imply that substitutions
will only be performed in files with the corresponding extension. However,
if a file matches *any* of the filename patterns, then *all* of the listed
substitutions will be performed. For example:
{{{
patterns = (
("*.css", (
r"""(url\(['"]{0,1}\s*(.*?)["']{0,1}\))""",
r"""(@import\s*["']\s*(.*?)["'])""",
)),
("*.js", (
r"whatever",
),
)
}}}
Not only will `url_converter()` be called for any occurrences of the word
"whatever" in JavaScript files, but also for any occurrences of
`url('something')` and `@import('something')` (in JavaScript files).
