Revision 67beb600563cf28186f44450e528df1ec4d524fd authored by Jeff King on 28 January 2014, 01:37:30 UTC, committed by Junio C Hamano on 28 January 2014, 19:59:49 UTC
When we see config like: [include] path the expand_user_path helper notices that the config value is empty, but we then dereference NULL while printing the error message (glibc will helpfully print "(null)" for us here, but we cannot rely on that). $ git -c include.path rev-parse error: Could not expand include path '(null)' fatal: unable to parse command-line config Instead of tweaking our message, let's actually use config_error_nonbool to match other config variables that expect a value: $ git -c include.path rev-parse error: Missing value for 'include.path' fatal: unable to parse command-line config Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
