Backout previous.
As Kristaps found out, i was wrong: .Bl -column phrases do not ignore
spacing rules for trailing punctuation in general.  In particular,
- the rightmost column of a column list is unaffected
- columns terminated by the .Ta macro instead of a tab are unaffected
- columns ending in a blank are unaffected
Spacing rules for trailing punctuation are only ignored when the tab
follows the punctuation immediately, without a blank in between,
because then the combination of punctuation and tab is treated by roff
as a word, and the punctuation is not recognized as isolated.
The reason this doesn't work in mandoc is that in the special case
of .Bl -column (not in general!), mandoc treats tabs as word delimiters.
We either need to solve this differently, or call it a bug in roff.
