We really do out best to make the spacing look as good as possible
(or at least consistent) but sometimes \TEX\ needs a bit of help.
An example of a helper is the following:
\startbuffer
\startlinecorrection
\input ward
\stoplinecorrection
\stopbuffer
\getbuffer[linecorrection]
When we use the same command with some left and/or right margins set, we get
this:
\startbuffer
\startnarrower
\startlinecorrection
\input ward
\stoplinecorrection
\stopnarrower
\stopbuffer
\getbuffer[linecorrection]
Here we do obey the margins inside the correction box but the box itself is still
as wide as the current width. A typical case where this happens is:
\startbuffer
\startitemize
\startitem an item:
\startlinecorrection
\input ward
\stoplinecorrection
\stopitem
\stopitemize
\stopbuffer
\getbuffer[linecorrection]
Here is a variant:
\startbuffer
\startitemize
\startitem a local linecorrection:
\startlocallinecorrection
\input ward
\stoplocallinecorrection
\stopitem
\stopitemize
\stopbuffer
\getbuffer[linecorrection]
Both types of correction wrap their content in a box and make sure that the
spacing around it is visually as good as possible. The local variant uses a box
fitting the available width taking margins into account and but resetting them
inside the box. The normal variant applies the margins inside the box. Which one
you use depends on the situation and content.
You can pass an optional argument that indicates the amount of spacing to be
added before and after the correction.
\startbuffer
\startlinecorrection[3*line]
\input ward
\stoplinecorrection
\stopbuffer
\getbuffer[linecorrection]
Normally you don't need this correction. It is mainly used for correcting spacing
around boxed material, like \type {\framed}:
\startbuffer
before
\startlinecorrection
\framed{something inbetween}
\stoplinecorrection
after
\stopbuffer
\getbuffer[linecorrection]
Because in this document we have set the whitespace this also gets added around
the box. So, in case your spacing around some special content looks bad, consider
using these commands.
