Keyword substitution: kv
Default branch: MAIN

tests/indent: don't create an unneeded file

indent: be strict about options from profile files

Previously, the "option" 'xdi0' was treated the same as '-xdi0'.

indent: do not report broken lines, report configuration on stderr

indent: clean up handling of whitespace

No functional change.

indent: remove accidental space before tab

indent: preserve indentation of preprocessor directives

tests/indent: explain, clean up and add some tests

indent: remove statistics

The numbers from the statistics were wrong.

indent: remove buggy code for swapping tokens

It is not the job of an indenter to swap tokens, even if it's only about
placing comments elsewhere.  The code that swapped the tokens was
complicated, buggy and impossible to understand.

In -br (brace right) mode, indent no longer moves a '{' from the
beginning of a line to the end of the previous line, as that was handled
by the token swapping code as well.  This change is unintended, but it
will be easier to re-add that now that the code is simpler.

indent: remove FreeBSD IDs

Most of the IDs were empty anyway.

tests/indent: use escape sequence for newline characters

No functional change.

tests/indent: test in-place formatting with parse errors

The file gets formatted until the end, despite the parse error. This may
destroy layout details of the code but usually preserves the overall
structure. Since all source code is supposed to be under version
control, this is not a problem.

indent: clean up lint annotation and tests

tests/indent: refine and extend tests

indent: fix handling of C99 comments after 'if (expr)'

indent: demonstrate controlled buffer overflow in C99 comment

tests/indent: test options without '-' in profile files

tests/indent: test several options '-P'

indent: clean up main_init_globals

No functional change.

indent: spell 'parentheses' properly in messages and comments

indent: parse option '-cli' strictly

indent: clean up format of warnings and errors

Previously, warnings and errors had the form of C block comments. Before
NetBSD io.c 1.20 from 2019-10-19, this format made sense because the
diagnostics could end up in the same output stream as the formatted
output.

Since NetBSD io.c 1.20 from 2019-10-19, all diagnostics are redirected
to stderr. This change was not mentioned in the commit message back
then, it makes sense nevertheless. Since stdout and stderr now are
properly separated, there is no need anymore to keep the weird format
for warnings and errors. Switch to the standard 'error: file:line'
format.

Move the function 'diag' to indent.c to have access to the name of the
current input file.

indent: fix line number counting at beginning of function body

indent/tests: demonstrate wrong line number counting

tests/indent: migrate remaining tests from t_indent to t_options

The test types_from_file was a subset of opt_U and thus has been
removed.

tests/indent: migrate integer options tests to t_options

tests/indent: migrate a few more tests to t_options

tests/indent: cover more error cases and inline indentation

tests/indent: provide full line coverage for argument handling
