Because of previous automated commits, such as changing 'guestfs___'
-> 'guestfs_int_', several function calls no longer lined up with
their parameters, and some lines were too long.
The bulk of this commit was done using emacs batch mode and the
technique described here:
http://www.cslab.pepperdine.edu/warford/BatchIndentationEmacs.html
The changes suggested by emacs were then reviewed by hand.
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.
