- Istream and Ostream now retain backslashes when reading/writing strings.
The previous implementation simply discarded them, except when used to
escape a double-quote or a newline. It is now vitally important to retain
them, eg for quoting regular expression meta-characters.
The backslash continues to be used as an escape character for double-quote
and newline, but otherwise get passed through "as-is" without any other
special meaning (ie, they are *NOT* C-style strings). This helps avoid
'backslash hell'!
For example,
string: "match real dots \.+, question mark \? or any char .*"
C-style: "match real dots \\.+, question mark \\? or any char .*"
- combined subfiles in db/IOstreams, some had more copyright info than code
- OPstreamI.H contained only private methods, moved into OPstream.C
Are these really correct?
IOstreams/Istream.H:# include "HashTable.C"
token/token.H:#define NoHashTableC
