[PATCH] docs: kdoc_output: only use out_tail when the identfier is shown

[Randy Dunlap <rdunlap@infradead.org>]

In -man mode, scripts/kernel-doc prints the "out_tail" information for
all symbols that are found (without the symbol info), whether the
symbols match the output selection criteria or not.

This can cause quite a lot of extraneous output in -man mode for the
symbols that are not in the selection criteria.

Modify kdoc_output.py so that it only calls out_tail() for symbols that
are being shown according to the selection criteria.
