commit 74e7888ed1d23eac05d097f9d635d4a58a6576a3
Author: Peter TB Brett <peter at peter-b.co.uk>
Commit: Peter TB Brett <peter at peter-b.co.uk>

    gschemdoc: Quote variables in case they contain spaces. [1792986]

    In the gschemdoc shell script, the variables $pdfreader and $browser
    need quoting on lines 86, 113 and 128 (eg "${browser}"). Otherwise,
    paths with spaces in, like "Program Files/Mozilla Firefox" commonly
    used in Windows don't work.

    Based on anonymous SourceForge patch.
