[Libguestfs] [PATCH v3 0/3] mllib: Various fixes and changes to Getopt module.
v2 -> v3: - Add M variant and test it. Rich.

[Libguestfs] [PATCH v3 1/3] mllib: getopt: Further fix int parsing.
Don't allow suffixes on integers, and fix the bounds to match the
definitions of Min_long and Max_long in <caml/mlvalues.h>.
Fixes commit 66b54bfefe42f2996d1b42c3646511bbd4349317.

[Libguestfs] [PATCH v3 2/3] mllib: Use L"..." and S '...' for long and short options.
There is also an M"..." variant which acts the same way as
L but handles the annoying virt-v2v two letter options.
