1. The first paragraph of a function's NSEdoc is used as a short
summary. Some of these were very long, so I split off a shorter summary.
2. Use asterisks (*) to denote bulletted lists, not 'o'
3. Wrap lines at 80 columns
4. a couple other spelling and formatting fixes
Using this regular expression, '\(\w*\)\s*=\s*\1\s*\.\.', found and
replaced many string concatenation-reassignments. These can cause
performance issues, since a new string gets allocated for each
reassignment. In many cases, the replacement is simply a single string,
wrapped across lines with the '\z' escape, which consumes a newline and
whitespace following it. In other cases, a table is used to hold the
substrings until the final string is built with a single table.concat
operation (same technique used in stdnse.strbuf).
Also, some string-building loops of this form:
s = ""
for i = 1, 100, 1 do
s = s .. "\0"
end
were replaced with this much faster and cleaner version:
s = string.rep("\0", 100)
