AnnotateModels needlessly regenerates identical annotations when wrapper_close matches column_pattern

[maxh]

The column_pattern regex here matched our wrapper_close string:

annotate_models/lib/annotate/annotate_models.rb

Line 510 in 5ac56e4

column_pattern = /^#[\t ]+[\w\*`]+[\t ]+.+$/

This caused old_columns == new_columns a few lines down to be false even though it should have been true.

(byebug) old_columns - new_columns
["# Schema information is auto-generated with: devbox rake annotate_models"]

Commands

$ rake annotate_models
Annotated (5): ...
$ rake annotate_models
Annotated (5): ... # unexpected: should be `Model files unchanged.` instead
