If the string also contains -# a `n' or `N', the code will use the numeric argument as the -# maximum number of errors if a numeric argument was given. If no -# numeric argument was given, the number from the value of this -# key will be used. E.g. with `compconf approximate_accept=2n' two -# errors will be accepted, but if the user gives another number -# with the numeric argument, this will be prefered. Also, with -# `compconf approximate_accept=0n', normally no correction will be -# tried, but if a numeric argument is given, automatic correction -# will be used. On the other hand, if the string contains an `!' -# and a `n' or `N', correction is not attempted if a numeric -# argument is given. Once the number of errors to accept is -# determined, the code will repeatedly try to generate matches by -# allowing one error, two errors, and so on.

If it is set to any non-empty -# value, the original string will be offered. If it contains the -# sub-string `last', the original string will appear as the last -# string when cycling through the corrections, otherwise it will -# appear as the first one (so that the command line does not -# change immediately). Also, if the value contains the sub-string -# `always', the original string will always be included, whereas -# normally it is included only if more than one possible -# correction was generated. -# -# approximate_prompt -# This can be set to a string that should be printed before the -# list of corrected strings when cycling through them. This string -# may contain the control sequences `%n', `%B', etc. known from -# the `-X' option of `compctl'.
