mandoc: Clarify the confusing "(text)" annotation in the character

[schwarze]

Log Message:
-----------
Clarify the confusing "(text)" annotation in the character lists.
In some cases, it meant "render as an ASCII character in output 
modes that have a notion of codepoints" (e.g. UTF-8, HTML); in other 
cases, "render in the text font in output modes that also provide
a special font for mathematical symbols" (e.g. PostScript, PDF).
Also explicitly annotate the escape sequences that use a special
font if available.
