Keyword substitution: kv
Default branch: MAIN

indent: miscellaneous cleanups, more tests for edge cases

indent: implement blank lines around conditional compilation

indent: remove broken code for handling blank lines

This fixes several bugs where blank lines were erroneously added or
removed, treating these old bugs for new bugs in different places.
These new bugs are expected to be easier to fix, as the old bugs will
not interfere anymore.

tests/indent: change directive from '#' to '//'

Using a '//' instead of '#' turns the directives into well-formed C
code, resulting in fewer error markers in the editor.

tests/indent: normalize amount of empty lines between test cases

indent: group global variables related to output control

No functional change.

indent: remove FreeBSD IDs

Most of the IDs were empty anyway.

tests/indent: refine and extend tests

indent: fix formatting of function definitions (since 2019-04-04)

In the definition of a function with a pointer return type, the
formatting depended on the name of the function.  Function names
matching [A-Za-z+] were formatted correctly, those containing [$0-9_]
weren't.

indent: rename blankline_requested variables

The words 'prefix' and 'postfix' sounded too much like horizontal
concepts, like in operators. The actual purpose of these variables is to
add blank lines before and after the current line, so use the same
wording as in the command line options.

No functional change.

tests/indent: merge duplicate input/output and output/output

No functional change.

tests/indent: restructure test for '-bacc' and '-nbacc'

To see the effects of the options, group the tests into sections, each
containing a small piece of code followed by the output of the two
options.

tests/indent: condense tests for bool options

Previously, each bool option such as '-bacc/-nbacc' had 6 test files:
input, options, output for the positive and negative option. Splitting
this test data into separate files made it harder than necessary to
quickly compare the test output from '-bacc' with that of '-nbacc'.

Have a single test for the positive and negative option, allowing
several tests to run on the same input with different options.

This commit only contains the rather mechanic changes of concatenating
the previous test files and inserting the '#indent' directives, which
are documented in t_options.sh. Removing duplicate input sections, as
well as other cleanups will follow soon.

No functional change.
