Move the g_strchomp() inside svUnescape(). It is part of the escaping process (although of course wrong to do, because it accepts "FOO= bar". That will be fixed later). Thereby, change the signature to allow in the future to do unescape without additional copy.

|
|
* Interface for non-destructively reading/writing files containing
|
|
* only shell variable declarations and full-line comments.
|
|
*
|
|
* Includes explicit inheritance mechanism intended for use with
|
|
* Red Hat Linux ifcfg-* files. There is no protection against
|
|
* inheritance loops; they will generally cause stack overflows.
|
|
* Furthermore, they are only intended for one level of inheritance;
|
|
* the value setting algorithm assumes this.
