 49. Fixed two issues in JIT. These were found by Karl Skomski with a custom
 LLVM fuzzer.
 
+50. The pcre2test program has been extended by adding the #newline_default 
+command. This has made it possible to run the standard tests when PCRE2 is 
+compiled with either CR or CRLF as the default newline convention. As part of 
+this work, the new command was added to several test files and the testing 
+scripts were modified. The pcre2grep tests can now also be run when there is no 
+LF in the default newline convention.

+  #newline_default [<newline-list>]
+.sp
+When PCRE2 is built, a default newline convention can be specified. This 
+determines which characters and/or character pairs are recognized as indicating
+a newline in a pattern or subject string. The default can be overridden when a
+pattern is compiled. The standard test files contain tests of various newline
+conventions, but the majority of the tests expect a single linefeed to be
+recognized as a newline by default. Without special action the tests would fail
+when PCRE2 is compiled with either CR or CRLF as the default newline.
+.P
+The #newline_default command specifies a list of newline types that are
+acceptable as the default. The types must be one of CR, LF, CRLF, ANYCRLF, or
+ANY (in upper or lower case), for example:
+.sp
+  #newline_default LF Any anyCRLF
+.sp
+If the default newline is in the list, this command has no effect. Otherwise,
+except when testing the POSIX API, a \fBnewline\fP modifier that specifies the
+first newline convention in the list (LF in the above example) is added to any
+pattern that does not already have a \fBnewline\fP modifier. If the newline
+list is empty, the feature is turned off. This command is present in a number
+of the standard test input files.
+.P
+When the POSIX API is being tested there is no way to override the default
+newline convention, though it is possible to set the newline convention from
+within the pattern. A warning is given if the \fBposix\fP modifier is used when
+\fB#newline_default\fP would set a default for the non-POSIX API.
