- * This code was included to provide a portable vsnprintf() and snprintf().
- * Some systems may provide their own, but we always use this one for
- * consistency.
- *
- * This code is based on snprintf.c - a portable implementation of snprintf
- * by Mark Martinec <mark.martinec@ijs.si>, Version 2.2, 2000-10-06.
- * Included with permission. It was heavily modified to fit in Vim.
- * The original code, including useful comments, can be found here:
- * http://www.ijs.si/software/snprintf/
- *
- * This snprintf() only supports the following conversion specifiers:
- * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
- * with flags: '-', '+', ' ', '0' and '#'.
- * An asterisk is supported for field width as well as precision.
- *
- * Limited support for floating point was added: 'f', 'F', 'e', 'E', 'g', 'G'.
- *
- * Length modifiers 'h' (short int) and 'l' (long int) and 'll' (long long int)
- * are supported. NOTE: for 'll' the argument is varnumber_T or uvarnumber_T.
- *
- * The locale is not used, the string is used as a byte string. This is only
- * relevant for double-byte encodings where the second byte may be '%'.
- *
- * It is permitted for "str_m" to be zero, and it is permitted to specify NULL
- * pointer for resulting string argument if "str_m" is zero (as per ISO C99).
- *
- * The return value is the number of characters which would be generated
- * for the given input, excluding the trailing NUL. If this value
- * is greater or equal to "str_m", not all characters from the result
- * have been stored in str, output bytes beyond the ("str_m"-1) -th character
- * are discarded. If "str_m" is greater than zero it is guaranteed
- * the resulting string will be NUL-terminated.
- */
-
-/*
- * When va_list is not supported we only define vim_snprintf().
- *
- * vim_vsnprintf_typval() can be invoked with either "va_list" or a list of
- * "typval_T". When the latter is not used it must be NULL.
