[Libguestfs] [PATCH] Fix small issues in documentations of APIs

- fix names of arguments & optional arguments in C<..> markers - use https for URLs where possible - fix links to other guestfs APIs - use more C<..> markers for special tests, shell commands, values of arguments, and names of fields - link to command man pages where an explicit command is mentioned - fix few incorrect documentation bits --- generator/actions_augeas.ml | 4 +- generator/actions_core.ml | 126 ++++++++++----------- generator/actions_core_deprecated.ml | 22 ++-- generator/actions_inspection.ml | 8 +- generator/actions_inspection_deprecated.ml | 10 +- generator/actions_properties.ml | 6 +- 6 files changed, 88 insertions(+), 88 deletions(-) diff --git a/generator/actions_augeas.ml b/generator/actions_augeas.ml index 3c419e2fc..bb0fe4db0 100644 --- a/generator/actions_augeas.ml +++ b/generator/actions_augeas.ml @@ -118,7 +118,7 @@ Defines a variable C<name> whose value is the result of evaluating C<expr>.
