[GSOC17] Smoke testing of all base utilities - Week 5

[Shivansh Rai]

Hello all,

Last week was spent in adding more functionalities to the smoke testing
tool. A summary of the updates can be viewed here [1] (the commit messages
are fairly descriptive).
An updated (generated) test file for ln(1) after introducing the changes in
tooling is available here [2].
*NOTE: *This test file only focuses on adding on negative test-cases since
the tool couldn't guess/construct a valid command for ln(1) ; but the tool
can also construct positive test-cases, and such tests will be added soon.

A differential for a minor fix was also made [3].
Summary: "stdbuf(1): Add buffer definition "B" to the usage message"

The plan for this week is to study the roff/groff type-setting system and
make the tool extract more relevant and useful information from the
man-pages.
