/* Functions for escaping unsafe characters in a string. The worst case
 * behaviour when `quoting', is that destination string is 3 times larger
 * compared to the source string. The used encoding is similar to the one used
 * for URL's, [a-zA-Z0-9_,.-] are considered safe. All the other characters
 * are converted to %XX, where XX is the 2digit hexadecimal representation of
 * the quoted character. In addition, '+' is also interpreted as a space. */
 
/* The most important ones if you are hand editing some place where encoded
 * strings are used (like the filenames in the repair fixfile) are probably:
 * ' ' = %20 or '+'
 * '%' = %25
 * '+' = %2b
