I had overlooked this earlier but noticed it during the review for my
previous patch that added --local_init and --global_init options. The
"convenience abbreviations" "hex" and "decimal" were set only if they do
not already have a value, but this test is early enough that there is no
way for them to have been given a value.

"decimal" to regexp fragments.
