matching any files, unless you happen to have files named with a
trailing comma in the current directory. If the pattern matches no
files, it is passed into Fossil's `main()` function as-is by the C
runtime system. Since Fossil uses commas to separate multiple glob
patterns, this means "all files at the root of the Fossil checkout
directory and nothing else."


## Experimenting

To preview the effects of command line glob pattern expansion for
various glob patterns (unquoted, quoted, comma-terminated), for any
combination of command shell and Fossil executable, on both POSIX
systems and Windows, the [`test-echo`][] command can be injected as
the first argument on the Fossil command line:

    $ fossil test-echo setting crlf-glob "*"
    $ echo * | fossil test-echo setting crlf-glob --args -

Moreover, the [`test-glob`][] command is handy to test if a string
matches a glob pattern.

[`test-echo`]: /help?cmd=test-echo
[`test-glob`]: /help?cmd=test-glob


## Converting `.gitignore` to `ignore-glob`

Many other version control systems handle the specific case of
ignoring certain files differently from fossil: they have you create
individual "ignore" files in each folder, which specify things ignored
in that folder and below. Usually some form of glob patterns are used
