The attached patch adjusts for a difference in behavior in the LVM
utilities 'lvs' and 'vgs'. The SLES10-SP2 versions of these (and
presumably others) append a trailing separator. This patch simply
adjusts the regexps to allow (but not require) this.
I thought just adding the ":?" to the regexps would do this, but this
was leaving the trailing separator in the last group match, so I ended
up tweaking the preceding group pattern as well.

Yeah, the \S+ is a greedy match, so it'd consume the ':' first. I don't
know if POSIX expressions have a non-greedy match modifir like Perl does.
That would let you do
(\\S+?):?
But in any case, your suggested modification is fine, so ACK.
BTW, what version of the LVM tools is SLES using - its probably useful
to note that in the comment you added, in case the same problem is
particular to a version, rather than just SLES

lvm2 2.02.17 (-7.19, x86_64)
But it's hard to know (without reading the ChangeLog in detail) how much
backporting is hidden in the distro-specific part of the version
(-7.19) ...

Okay, looks simple and well contained.
Applied and commited,
thanks !
