[PATCH v3] help: interpret boolean string values for help.autocorrect
From: Scott Chacon <schacon@gmail.com>
A help.autocorrect value of 1 is currently interpreted as "wait 1 decisecond", which can be confusing to users who believe they are setting a boolean value to turn the autocorrect feature on.
Interpret the value of help.autocorrect as either one of the accepted list of special values ("never", "immediate", ...), a boolean or an integer. If the value is 1, it is no longer interpreted as a decisecond value of 0.1s but as a true boolean, the equivalent of "immediate". If the value is 2 or more, continue treating it as a decisecond wait time.
False boolean string values ("off", "false", "no") are now equivalent to "never", meaning that guessed values are still shown but nothing is executed. True boolean string values are interpreted as "immediate".

help: interpret boolean string values for help.autocorrect
Basically just using Junio's suggested code from the ML, splitting most
of the logic out into a parse_autocorrect method and then special casing
a 1 integer as "immediate". I reverted to interpreting false boolean
values as NEVER rather than 0, which means they no longer show guesses,
which the last patch did.
Changes since v2:
* split out most logic into parse_autocorrect
* interpret false boolean values as NEVER rather than 0
* Update the help.txt documentationPublished-As: https://github.com/gitgitgadget/git/releases/tag/pr-git-1869%2Fschacon%2Fmaster-v3

- False boolean string values ("off", "false", "no") are now equivalent to 0,
- meaning that guessed values are still shown but nothing is executed (as
- opposed to "never", which does not show the guesses). True boolean string
- values are interpreted as "immediate".
