There are three kinds of input lines: text lines, macros taking

positional arguments (like Dt Fn Xr) and macros taking text as
arguments (like Nd Sh Em %T An).  In the past, even the latter put
each word of their arguments into its own MDOC_TEXT node; instead,
concatenate arguments unless delimiters, keeps or spacing mode
prevent that.  Regarding mandoc(1), this is internal refactoring,
no output change intended.

Regarding mandocdb(8), this fixes yet another regression introduced
when switching from DB to SQLite: The ability to search for strings
crossing word boundaries was lost and is hereby restored.  At the
same time, database sizes and build times are both reduced by a bit
more than 5% each.
