Re: [Libguestfs] [PATCH] When calling getline first time, initialize length to zero.

The man page for getline says: ssize_t getline(char **lineptr, size_t *n, FILE *stream); [...] If *lineptr is set to NULL and *n is set 0 before the call, then get‐ line() will allocate a buffer for storing the line. This buffer should be freed by the user program even if getline() failed. which seems to indicate that we must initialize both line and len to 0 before the first call to getline. In several places we were not initializing len. The program still worked fine, but it seems better to initialize the length anyway. ---
