Finish implementation of --all
* doc/cflow.1: Document the --all --all behavior * doc/cflow.texi: Likewise. * src/main.c: Increment all_functions for each -A option. * src/output.c (tree_output): If one --all option is used, output graphs for all top-level functions (i.e. functions, not reachable from other ones). If used twice, output graphs for all global function. * tests/all.at: New test. * tests/Makefile.am: Add new test. * tests/testsuite.at: Likewise.
