Earlier while working on the big completer rework series, I managed to break (gdb) [TAB] locally, and make GDB crash, but only notice a few weeks down the road, because we have no test for that... I also noticed that: (gdb) [TAB] didn't work (didn't show all commands as matches), even though entering a command with leading whitespace works: (gdb) help This commit fixes the latter and adds a testcase that covers both issues. The gdb.base/completion.exp change is necessary because the new test has a file name that also starts with "gdb.base/complet", making that particular test ambiguous. Adding another letter disambiguates. gdb/ChangeLog: 2017-11-25 Pedro Alves <palves@redhat.com> * completer.c (complete_line_internal_1): Skip spaces until the start of the command. gdb/testsuite/ChangeLog: 2017-11-25 Pedro Alves <palves@redhat.com> * gdb.base/complete-empty.exp: New file. * gdb.base/completion.exp: Adjust.
