Subject: [PATCH] Fix a bug on name parsing at the end of current input buffer
|
|
|
|
For https://bugzilla.gnome.org/show_bug.cgi?id=754946
|
|
|
|
When hitting the end of the current input buffer while parsing
|
|
a name we could end up loosing the beginning of the name, which
|
|
led to various issues.
