11 * Parse value of the argument to the "filter" keyword.
12 * On the command line this looks like:
13 * --filter=<arg>
14 * and in the pack protocol as:
15 * "filter" SP <arg>
17 * The filter keyword will be used by many commands.
18 * See Documentation/rev-list-options.txt for allowed values for <arg>.
20 * Capture the given arg as the "filter_spec". This can be forwarded to
21 * subordinate commands when necessary. We also "intern" the arg for
22 * the convenience of the current command.
