Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
only skip .gdbinit install if files differ (bug #53241) * Makefile.am (gdb-install-rule): Rename from gdb_install_rule. Change all uses. Don't skip installation if files are the same. (.gdbinit): Use $(AM_V_GEN) for more consistent output. * test/module.mk: Don't install .gdbinit file in test subdirectory of build tree.
