[libvirt] [PATCH] maint: avoid excess parens in STREQ

[Eric Blake]

* src/internal.h (STREQ, STRCASEEQ, STRNEQ, STRCASENEQ, STREQLEN)
(STRCASEEQLEN, STRNEQLEN, STRCASENEQLEN, STRPREFIX): Avoid
redundant parenthesis.
* examples/domain-events/events-c/event-test.c (STREQ): Likewise.
* src/storage/parthelper.c (STREQ): Likewise.
---
These macros were originally inspired by Jim Meyering, who has since made
this same cleanup elsewhere.  For example:
