string, reallocating the string if necessary. Add an openpam_readword() function that reads a single word from a file according to the usual shell quoting rules. Add an openpam_readlinev() function that uses openpam_readword() to read an entire line and return a list of the words it contained. Rewrite openpam_parse_chain() using openpam_readlinev(), which greatly simplifies the code and ensures correct parsing of module option. Thanks to Maëlle Lesage for pointing out the issue and writing an early version of what became the main loop in openpam_readword(). git-svn-id: svn+ssh://svn.openpam.org/svn/openpam/trunk@547 185d5e19-27fe-0310-9dcf-9bff6b9f3609
