Subject: glsl: Don't print a useless space at the end of an S-Expression list.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2c23ac82a4038c0f69b6ce5b0c49f763a65df8a;p=mesa.git

glsl: Don't print a useless space at the end of an S-Expression list.

We really only want to print spaces -between- elements, not after each
element.  This cleans up error messages from IR reader, making them
(mildly) easier to read.
