Like less, w3m can use an input preprocessor when displaying files. The preprocessor command is taken from the environment variable LESSOPEN. The command line in LESSOPEN should include one occurrence of the string "%s", which will be replaced by the filename when the input preprocessor command is invoked. Giving more than one "%s" - or a any other conversion specifier - will lead to undefined behaviour. Add a check to make sure the command given has only one "%s".
