[PATCH:xts 11/16] xts5: Add parentheses around assignment in an if.

[Cyril Brulebois]

Tell compilers we really meant to assign and then check.

The following warning goes away accordingly:
|   CC     nextvclass.lo
| nextvclass.c:224:14: warning: using the result of an assignment as a condition without parentheses [-Wparentheses]
|                         if (comma = strchr(++s, COMMA))
|                             ~~~~~~^~~~~~~~~~~~~~~~~~~~
| nextvclass.c:224:14: note: use '==' to turn this assignment into an equality comparison
|                         if (comma = strchr(++s, COMMA))
|                                   ^
|                                   ==
| nextvclass.c:224:14: note: place parentheses around the assignment to silence this warning
|                         if (comma = strchr(++s, COMMA))
|                                   ^
|                             (                         )
