Re: [python][patch] PR python/19151 Hardware breakpoints in GDB Python.

[Pedro Alves <palves@redhat.com>]

Hi Phil,

I agree with Eli, this should be mentioned in NEWS, as all
Python API additions/changes do.

Some nits below, but otherwise looks fine.

Please post a v2 with a NEWS entry, including the proposed
git commit log, and it should be good to go.

Mention "(pybp_codes)":

  	* python/py-breakpoint.c (pybp_codes): Add hardware
        breakpoint constant gdb.BP_HARDWARE_BREAKPOINT.

Double space after '.' and missing '.' at end of second sentence.

Missing "return"

               ^^ spurious double space.

Leading ".*" not necessary, it's implied.

> +	"Set hardware breakpoint"

Lowercase "Set".

Leading ".*" not necessary, it's implied.

Lowercase "Check".  I'd remove "check, even, since all tests
are checking something:

	"info breakpoints shows a hardware breakpoint"
