man.indent.refsect boolean man.indent.refsect Adjust indentation of refsect* and refsection? If the value of man.indent.refsect is non-zero, the width of the left margin for refsect1, refsect2 and refsect3 contents and titles (and first-level, second-level, and third-level nested refsectioninstances) is adjusted by the value of the man.indent.width parameter. With man.indent.width set to its default value of 3n, the main results are that: contents of refsect1 are output with a left margin of three characters instead the roff default of seven or eight characters contents of refsect2 are displayed in console output with a left margin of six characters instead the of the roff default of seven characters the contents of refsect3 and nested refsection instances are adjusted accordingly. If instead the value of man.indent.refsect is zero, no margin adjustment is done for refsect* output. If your content is primarly comprised of refsect1 and refsect2 content (or the refsection equivalent) – with few or no refsect3 or lower nested sections , you may be able to “conserve” space in your output by setting man.indent.refsect to a non-zero value. Doing so will “squeeze” the left margin in such as way as to provide an additional four characters of “room” per line in refsect1 output. That extra room may be useful if, for example, you have many verbatim sections with long lines in them.
