URLM_LIST_BROWSERS

Show the browser definition list. Items are listed in the same
format as used to define them: <browser>:<name>:<cmd-format>. The
default browser is marked with [*].

Note: urlm_add_browser, urlm_del_browser, and urlm_list_browsers store
the actual browser list as a string in the setting urlm_browsers. The
format of this setting is prickly; you shouldn't modify it directly.
