Victor Engmark 2ff6c34612 userdiff: support Bash
Support POSIX, bashism and mixed function declarations, all four
compound command types, trailing comments and mixed whitespace.

Even though Bash allows locale-dependent characters in function names
<https://unix.stackexchange.com/a/245336/3645>, only detect function
names with characters allowed by POSIX.1-2017
<https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_235>
for simplicity. This should cover the vast majority of use cases, and
produces system-agnostic results.

Since a word pattern has to be specified, but there is no easy way to
know the default word pattern, use the default `IFS` characters for a
starter. A later patch can improve this.
